6(4x+5)=3(x+8)+3 round to the nearest hundredth

Mathematics
1 answer:
My name is Ann [436]3 years ago
8 0

Answer:

x = -0.14

Step-by-step explanation:

Given that:

6(4x+5)=3(x+8)+3

By simplifying:

24x + 30 = 3x + 24 +3

Taking terms with x to left side and others on right side

Sign will be changed when transferring term from one side to other

24x - 3x= 24 + 3 -30

21x = 27 - 30

21x = -3

x= -3/21

x= - 0.142857...

By rounding off to nearest hundredth

  • As the third decimal place (2) is smaller than 5
  • Previous digit will remain same so,

x = -0.14

I hope it will help you!

For a Saturday matinee, adult tickets cost $8.50 and kids under 12 pay only $7.00. If 80 tickets are sold for a total
jolli1 [7]

Answer:

  • 30 adult tickets,
  • 50 kids tickets

Step-by-step explanation:

<u>Given</u>

  • Cost of adult ticket = $8.50
  • Cost of kids ticket = $7.00
  • Number of tickets = 80
  • Total cost = $605

Let the adult ticket be a and kids be k

<u>We got equations</u>

  • a + k = 80
  • 8.5a + 7k = 605

<u>From the first equation we get</u>

  • k = 80 -a

<u>Substituting k in the second equation</u>

  • 8.5a + 7(80 - a) = 605
  • 8.5a - 7a + 560= 605
  • 1.5a = 45
  • a = 45/1.5
  • a = 30

<u>Then finding k</u>

  • k = 80 - 30 = 50

Angels Inscribed and circumscribed.
zhenek [66]

Remark

The diameter of the circle is AC. The hypotenuse of the right triangle is also AC. This assumes that A,B and C all lie on the circumference of the circle.

Answers

One

The center of the circle is on the diameter of the circle. In fact, the center bisects the diameter. So the center lies on AC and if the center is labeled O then AO = BO.

<em><u>Answer 1: </u></em> AC

Two

The answer is the single word diameter.
